  2. What is a Simple Machine? • A simple machine has few or no moving parts. • Simple machines make work easier by changing the amount or the direction of the force used to do work.

  3. There are six types of simple machines. • wheel and axle • pulley • incline plane • wedges • screw • lever

  4. Wheel and Axle • A wheel that turns on a post to help move things quickly and easily. • Gears are a form of wheels and axles. • Examples: doorknob, steering wheel, and a screwdriver

  5. Pulley • Made of rope and string wound around a reel to change the direction of a force. • A pulley needs a rope, chain or belt around the groove to make it do work. • Examples: crane, fishing pole, clothes line, and a flagpole

  6. Inclined Plane • An inclined plane is a flat surface that is higher on one end. • Inclined planes make the work of moving things easier. • Examples: ramp, and stairs

  7. Wedge • Two inclined planes together used to raise an object or split an object. • A wedge is used to split things. • Examples: knife, and an ax

  8. Screw • An inclined plane wrapped around a pole or shaft that is used to hold materials together or drill holes. • The inclined plane allows the screw to move itself when rotated. • Examples: drill bit, and screws

  9. Lever • Made of a board or bar set on top of a fulcrum. • It is used to lift weight. • Examples: seesaw, crowbar, baseball bat, and a rake

  10. Two simple machines, make a compound Machine • Two or more simple machines working together. • Examples: bike and a car

  11. Lesson: Students will have to make a kid inspiration chart then exchange with a partner for assessment.

  12. Lesson: Students will have to make a bar graph of how many of each simple machine they found in their group.
